ADDITIONAL INFORMATION for ATP5

SUMMARY PARAGRAPH for ATP5

ATP5 encodes the oligomycin sensitivity-conferring protein (OSCP), a subunit of mitochondrial ATP synthase that is homologous to the delta subunit of bacterial ATP synthase (4). The ATP synthase complex utilizes proton motive force to generate ATP from ADP and Pi (4). The structure of this enzyme complex is highly conserved among diverse organisms and consists of two major components, soluble F1 and membrane-bound F0, each of which contains many subunits. F1 and F0 are connected, both functionally and physically, via two additional multi-subunit structures, the central stalk and the stator stalk. OSCP is part of the stator stalk, a stationary structure necessary for the productive transmission of rotary motion from the F0 proton pump to the F1 catalytic core (4 and 5 and references therein).

Although ATP5 is essential for ATP synthase function, it is not essential for life in yeast. Deletion of ATP5, like deletions in many genes necessary for the function or maintenance of mitochondria, leads to a "petite" phenotype that is slow-growing and unable to survive on nonfermentable carbon sources (1).

General ATP synthase structure and function are reviewed in references 4 and 5. For a review that is specific to yeast, see reference 6.
